Tim Smedley travels the world to work out why air pollution occurs, and what we can do to solve the problem
Intrigued by some casual facts and figures he’d stumbled across in a newspaper, Smedley investigated further, then decided to travel around the world to look at the factors affecting air quality in major cities. Along with examples of how air pollution occurred and some frightening statistics – some compiled from his own measurements using a hand-held air pollution monitor – the author suggests practical ways individuals can make a tangible difference to the quality of air in their communities.
